Video: A Look at Some of the Developer Tools Built-in To Ice Cream Sandwich


We were poking around in the latest Ice Cream Sandwich (Android 4.0.1) build for the Nexus S that came out over the weekend and noticed that a special “Developer options” section has been included. Inside, you will find a whole mess of features that can be toggled to help you monitor the performance of your phone, test settings, perform demos, and probably most importantly, manage how Android handles currently running tasks. We put together a quick screencast of the section up above, highlighting many of them.

Developers, excited?

  • Hmm, the option to make the transitions slower should just be called “Toggle Sense On/Off”

  • It’s very nice of them. I haven’t seen such a developer section on any device before. It’s another tasty thing Android 4.0. offers for developers

    All of this will be removed on Verizon phones. Mark my words.

    Is it just me or does this kinda hint towards a possibly unlockable bootloader? Maybe at some point (fingers crossed!!)

      All Nexus devices have unlockable bootloaders ….. You can unlock them with fastboot.

        Sweet! I knew the others were but I thought I read somewhere that Verizon interfered with that. Makes sense though.

    I loved every second of this (that is until the end when I saw the AT&T text)…

    • I agree… just popped outta nowheres…

  • Dominick DeVito

    Got the SDK updated, ready to start migrating my apps to ICS – have a Xoom and hope it gets ported soon. Just wish there was a phone to deploy this to. Now which phone could suffice I wonder… :p

      Razr or bionic might suffice, SPEC-WISE that is

  • yesyesyesyesyes

  • yay if only i could have it

  • Jeremy Edwards

    Yes. I like the auto close activity on exit.

    • why didnt you force GPU rendering. Ive heard it makes apps run a lot better.

      • Jeremy Edwards

        Hardware accelerated rendering allows for apps to animate smoother because that work is offloaded to the GPU. It’s not a magic bullet for Android’s performance problems. I’d say over 80% of Android’s performance problems are basically thread related. Expensive tasks being done in the UI thread. You can tell because the app will just randomly hard pause a lot when you do something interactive like scrolling a list. It looks like it wants to go fast but it shudders like crazy because something like disk io is holding it up.

    Better an  Better

  • woohoo

  • What’s the name of the app that recorded the screen?

    • Jeremy Edwards

      I believe they use HDMI output and this device to record the screen output. http://www.blackmagic-design.com/products/intensity/

        No. They just used the screencast app https://market.android.com/details?id=com.ms.screencast&feature=search_result#?t=W251bGwsMSwxLDEsImNvbS5tcy5zY3JlZW5jYXN0Il0.

        • Jeremy Edwards

          This looks pretty sweet. They use the HDMI output definitely for tablets though. They mentioned that at Google IO 2011 in some video.
